Theology with My Daughter

A: Daddy, my teacher said that when Jesus comes back there won't be any night. Is that right?

Matt: Yeah, that's right. There won't be any night, because Jesus will be the light. We won't even need the sun. Isn't that weird?

(She thinks about this for a while.)

A: Is it because of his legs?

Matt: What?

A: Is it so bright because of his legs?

Matt: I don't understand.

A: Are his legs so white that it makes it so we don't need any sun?

Where does this come from? I don't know.
